Adjusting Fractional Dimension Horizontal Number Spacing?

When fractions occur in dimensions, there is a large gap between the integer and the fraction (ie. in 3 1/2", btw the 3 and the 1/2). it would be nice to be able to tighten this space to avoid overlaps. No setting I can find in Annotation Styles addesses this. the closest thing is “stack height scale” under “length units,” which compresses the fractin vertically but leaves the same gap between the fraction and the whole number.

thanks for reporting, I logged this as RH-71619 Fractional dimensions have too spacious kerning

RH-71619 is fixed in the latest WIP

Thank you!
